Seminar | Synthesis of Ceramic Oxides Nanoparticles: From Polymeric Precursors to Colloidal Synthesis Process, by Professor Edson Leite

Wednesday, January 16, 2019 3:30 pm - 3:30 pm EST (GMT -05:00)

Please join the Department of Chemical Engineering on Wednesday, January 16, 2019 for a guest lecture by Professor Edson Leite, Scientific Director of the Brazillian Nanotechnology National Laboratory and Professor in the Chemistry Department at Federal University of São Carlos, speaking on the synthesis of ceramic oxides nanoparticles. 

Abstract

The synthesis of nanometric particles (nanoparticles) of ceramic materials has been consolidated in the last two decades as a multidisciplinary research area, aiming to obtain control over the phase purity, as well as in the shape, size, size distribution and degree of agglomeration of the nanoparticles. In general, this degree of control is possible only through the use of chemical synthesis routes, because those methods allow for better control of the process at a molecular level. In this lecture, Professor Leite will report the advantages and disadvantages of the synthesis routes based on the Pechini method and on colloidal methods mainly based on the non-hydrolytic sol-gel route. Results related to the control of the size, shape, and degree of particle agglomeration will be presented, especially for oxides such as SnO2 (doped and undoped), ZrO2, TiO2, PbTiO3, and SrTiO3.

Biographical Sketch

Edson Roberto Leite is a Professor in the Chemistry Department at the Federal University of São Carlos (in São Carlos, SP-Brazil) and Scientific Director of the LNNano-CNPEM. He received his BS and MS degrees in Materials Science and Engineering from the Federal University of São Carlos in 1988 and 1990, respectively. In 1988, he was with 3M of Brazil, where he engaged in the research and development of electronics and telecommunications products and received his PhD in Materials Science and Engineering from the Federal University of São Carlos in 1993. In January 1994, he joined Chemistry Department at Federal University of São Carlos. From 1998 to 1999, Edson was Visiting Professor of Materials Science and Engineering, Lehigh University, Bethlehem, PA.

His current research interests include synthesis and growth process of inorganic nanoparticles by chemical approaches, materials characterization by electron microscopy, thermal stability of nanostructured materials and materials for photoelectrochemistry devices and solar water splitting. He has published more than 300 scientific papers and edited three books (related to materials for energy) and is a co-author of one book (related to nucleation and growth process in nanocrystals).

He has received several awards, including Scopus Prize for the remarkable scientific production from Elsevier /CAPES(2006) and the John Simon Guggenheim Memorial Foundation Fellowship for the development of scientific research related to the thermal stability of ceramics nanosystem from John Simon Guggenheim Memorial Foundation (2009). In 2012, Edson was nominated Member of the World Academy of Ceramics. In 2014, he was Co-Chair of the MRS Spring Meeting in San Francisco. He is Principal Editor of the Journal Materials Research (JRM) and Journal of Nanoparticle Research (JNR).
